Malaoxon (Liromat, Malation oxon, Malthon oxon) is a
phosphorothioate. It is a breakdown product of, and more toxic than, malathion
.
Air and water
This chemical may be sensitive to prolonged exposure to air.[1] Slightly water-soluble.
Fire hazard
This chemical is combustible.[1]
Health hazard
Symptoms of exposure to this type of compound include cholinesterase inhibition,
axonopathy and paresthesias and paralysis of limbs. A decrease in blood pressure may occur. Respiratory failure
may also occur.
Acute/chronic hazards
This compound is toxic by ingestion. It is a cholinesterase inhibitor. When heated to decomposition, it emits toxic fumes of sulfur oxides and phosphorus oxides.[1]
Reactivity profile
A thioorganophosphate,
exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals
and hydrides.
